hi @ChefenFN ,
Found the reference to Audio Filters which use the automated check for moderation
from the document at Intellectual Property (IP) and DMCA Guidelines for Fortnite Island Creators
Any license of the content must be broad enough to grant Epic a license consistent with the Fortnite Island Creator Rules.
Please note that content that is blocked by our audio filter, which is intended to keep infringing content out of Fortnite, cannot be published at this time, even if you have otherwise obtained a license.
Even if third party intellectual property otherwise exists in Fortnite (such as Locker items and Characters based on movie or TV characters), you do not have the right to use that content to create your island without a separate license from that third party.
